How come orange juice is available all year round and always tastes exactly the same – regardless of the brand – all round the world? Actually, it’s very simple. First, the oranges are pressed, then the juice is sealed in giant tanks where all the oxygen is removed to prevent it from going mouldy. This process keeps the juice perfectly preserved for up to a year. Then flavour enhancers are added to standardise the taste. Fun fact: that “orange juice” taste is often manufactured by the perfume industry.
